...or defuse/reset them whenever a player who is using the Tazer comes along (but it has to be selected as your active weapon or it won't work).

So they would be ineffective against the holder of the Tazer, but still be effective against the rest of the players?

This would make the Tazer a much welcomed addition to the world of Goldeneye multiplayer I think, especially if you could hack the proximities and use them as Remote Mines at any time, whenever a player gets near them, the Tazer could beep, one tap of the alternative fire button and BANG! This would make the Tazer a very cool gadget to have in proximity multiplayer, it could also lead to some very cool new game types... Oooh... too many ideas are circling my head, I'm off for a coffee.
